Abstract

The study is composed of three phases to describe the paintings at normal and several aging times: modeling of new icons similar to an ancient one, aging of the icons by heat and ultraviolet irradiation, and characterization of the icons. The results showed a change in the chemical structure of the painting materials, the crystallinity of the wood and canvas materials, and the chromaticity coordinates with darkening in the heat treatment and fading in the UV irradiation treatment. There is a correlation between the exposure time, the chemical properties of the materials, and the optical properties of the paintings.

一种全面的分析方法,用于监测暴露于环境风险后的绘画的物理化学变化

摘要

这项研究由三个阶段组成,分别描述在正常和数个老化时间下的绘画:模拟与古代相似的新图标的建模,通过加热和紫外线照射对图标进行老化以及对图标进行表征。结果表明,涂​​料的化学结构,木材和帆布材料的结晶度发生了变化,并且在热处理中色度坐标随着变暗而在紫外线辐射处理中随着褪色而变化。曝光时间,材料的化学性质和绘画的光学性质之间存在相关性。
